2 Claims.

The invention relates to smoking devices or holders for cigarettes or cigars.

One object of the invention is to provide a cigarette or cigar holder which is provided with eflicient means for retaining the tobacco juices and condensate from the smoke in the holder to prevent them from reaching the mouthpiece, and includes a tubular casing and a core which is slidably mounted in the casing and serves when slid in one direction to eject the cigarette or cigar.

Another object of the invention is to provide a holder of this type in which the assembled core and mouthpiece are slidably retained in the tubular casing for conjoint removal for cleaning purposes.

Another object of the invention is to provide a holder of the ejector type which is efiicient in use and can be fabricated at a low cost.

Other objects of the invention and the various advantages and characteristics of the present holder will appear from the following detailed description.

The invention consists in the several features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.

In the drawing:

Fig. l is an enlarged longitudinal section of a holder embodying the invention, the core being v shown in elevation.

Fig. 2 is a perspective showing the assembled core and mouthpiece and the screw collar for slidably retaining the latter in the tubular casing, separated from the casing for cleaning.

Fig. 3 is a longitudinal section of the core.

Fig. 4 is a section taken on line 44 of Fig. 1.

Fig. 5 is a section taken on line 55 of Fig, 1.

Fig. 6 is a perspective of the screw-collar for slidably retaining the core with the mouthpiece attached in the tubular casing.

The invention is exemplified in a holder which comprises a tubular casing I, having its end '8 adapted to receive the tip of a cigarette; and a core, generally designated I3, slidably fitting in and rotatable in the bore 9 of the casing, and provided with an integral stem ID to which is attached a mouthpiece II with a draft-duct I2.

The core I3 is provided with a cylindrical outer end I4 and a cylindrical inner end I5 which slidably and rotatably fit within the bore 9 of the casing I. Between these cylindrical ends, the core is substantially triangular in cross-section in order to provide three flat sides which form three transversely separated chambers I6 I I and It. The

latter are segmental in cross-section and extend longitudinally between the cylindrical ends I4 and I5. The core i3 is provided at its outer end I4 with an angular or L-shaped duct 29 which communicates with the portion of the bore 9 in which the cigarette is held and the chamber l6 between the core and the casing. A notch 2I adjacent the cylindrical inner end I5 of the core forms a passage between chambers I6 and I1; and a notch 22 adjacent the cylindrical outer end I4 of the core forms a passage between chambers I! and I8. A duct 23 communicates with chamber I8, extends longitudinally to the inner end of the stem ID on the core I3, and communicates with the draft-duct I2 in the mouthpiece II.

The mouthpiece I I is provided at the end thereof that is nearer the casing l with a cylindrical portion 25 which slidably and rotatably fits in cylindrical bore 26. The latter is formed in an integral longitudinal extension 27 of the casing. The stem I0 on core I3 is secured to the mouthpiece II by a screw-thread connection 28. The mouthpiece I I is adapted slidably to shift the core I3 in bore 9 of casing 'I and also to rotate the stem I0 and core I3. The cylindrical portion 25 of mouthpiece I I is guided in the bore 26 for this purpose.

The core I3 and stem II] are held for limited sliding movement in the casing 'I and extension 21 by a collar 39 which is provided with a male screw-thread 3! for engaging a female screwthread in the central portion of the casing. The collar 30 seats against a shoulder 32. The stem ID on the core I3 is triangular in cross-section, as at 33, and extends through a correspondingly shaped opening 34 in collar 30. Because of this the stem is permitted to slide through the collar and when slid forwards it releases or ejects the cigarette. Because the stem is triangular rotation of the mouthpiece II in one direction serves to unscrew the collar and thus release the core I3 and mouthpiece I I for removal from the easing. A coil spring 36 in extension 21 of easing I is interposed between the collar 39 and the inner end of mouthpiece II and yieldingly holds the mouthpiece and core in their retracted position in the casing.

The operation of the device will be as follows L when the device is assembled and a cigarette is held in the outer end of the casing I, the draft applied to the duct I2 in mouthpiece I I will draw the smoke successively through duct 20 into chamber I6, longitudinally through chamber I6, through notch 2|, longitudinally through chamher l1, through notch 22, and longitudinally through chamber l 8, and into duct 23, which communicates with the draft-duct l2. This sinuous path of the smoke will cause the tobacco juices and the condensate from the smoke to be re tained in the chambers between the core and the casing. When it is desired to eject the cigarette, the mouthpiece H is pushed forwards while the casing is held, and end I4 of the core 13 will then eject the cigarette from the casing 7. After this ejection, the mouthpiece will be released and spring 36 will retract the core l3 and mouthpiece H to their normal position. When it is desired to clean the device and remove the accumulated juices and condensate in the bore 9, the casing l and the core [3, the user will rotate the mouthpiece II and the attached stem l which rotates therewith, so that said stem will rotate collar 30 and unscrew it from the casing until it is free, so it will permit the core l3, collar 39, spring 36 and mouthpiece I! to be withdrawn from the casing. The core and mouthpiece may remain assembled after removal from the casing, as shown in Fig. 2. The core I3 and the bore 9 of the casing 1 may be easily cleaned. After being cleaned, the core l3 will then be inserted through extension 21' into the bore 9 of the casing 7 and the mouthpiece ll will be inserted in extension 21 until collar 30 meets the screw-thread in the casing. The mouthpiece will then be rotated in the proper direction to cause collar 38 to become connected to the screw-thread and seated against shoulder 32. The core and mouthpiece will then be restored to their operative relation to the casing.

In practice the mouthpiece may be formed of any suitable material and the casing and core may be formed of metal, such as aluminum. The screw-thread 28 between mouthpiece l l and stem it) permits the collar 38 and spring 36 to be assembled with the core [3 and mouthpiece H.

The construction described exemplifies a holder in which the mouthpiece, stem and core are slidably mounted in the casing for removal of the cigarette and the tobacco juices and the condensate from the smoke are entrapped in the chambers between the core and the casing. It also exemplifies a holder wherein rotation of the mouthpiece efiects either connection or disconnection of the core and mouthpiece with respect to the casing.

While the holder has been described more particularly for a cigarette, it will be understood that it may also be used for smoking cigars, without change in construction other than the shaping of the holding end of the casing.

The invention is not to be understood as limited to the details described, since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Paten is:

1. A smoking device comprising a tubular casing having one of its ends adapted to hold an article for smoking, a core extending longitudinally of, and slidable and rotatable in the casing, adapted when slid in the direction of said one end of the casing to eject the article from the casing, and provided at one of its ends with an inletduct for smoke, at its other end with an outletduct and with means between said ends and independent of the ducts for retaining tobacco juice and condensate from the smoke within the casing, a mouthpiece disposed normally at the other end of the casing, connected to the core for sliding and rotative movement therewith, and provided with a-draft-duct communicatively connected to receive smoke from the outlet-duct in the core, and a collar extending around and serving to support the core and connected by a screwthread connection to the interior of the casing, the core being non-circular in cross section and the collar having its interior of corresponding cross section in order that turning of the core by the mouthpiece causes connection or disconnection of the collar with respect to the casing.

2. A smoking device comprising a tubular casing having one end thereof adapted to hold an article for smoking and embodying at its other end an integral extension, a core extending longitudinally of, and slidable and rotatable in the casing, adapted when slid in the direction of said one end of the casing to eject the article therefrom, and provided at one of its ends with an inlet-duct for smoke, at its other end with an outlet-duct and with means between the said ends for directing the smoke longitudinally back and forth and retaining tobacco juice and condensate from the smoke within the casing, a mouthpiece having its inner end slidable and rotatable in said extens on and provided with a draft-duct, a stem of polygonal cross section connected fixedly to the end of the core that is opposite the mouthpiece, removably and rotatably connected to the mouthpiece, and provided with a duct communicating with the outlet-duct in the core and the draft-duct in the mouthpiece, a retaining collar extending around and serving slidably to support the stem, connected to the casing by a screw-thread connection, and adapted in response to turning of the stem by the mouthpiece to be brought into connected or disconnected relation with the casing, and a spring in the extension between the collar and the mouthpiece for retracting the mouthpiece and the stemequipped core, the collar, core, stem, spring and mouthpiece being conjointly and slidably removable when the collar is disconnected from said screw-thread.
